Installing the 575 Power Supply (continued)
If you have a PPX:575–6663 power supply module, ensure that your voltage
selection matches your line voltage. To configure the module for 110 VAC or
220 VAC operation, use the jumper selector wire located on the power
supply board. See Figure 4-9.

CAUTION
The PPX:575–6663 power supply has selectable voltage. Ensure that the voltage
selector is set to match the input power. See Figure 4-9 for an example of how
to set the voltage selector.
Attempting to operate the power supply at 220 VAC with 110 VAC selected, or
110 VAC with 220 VAC selected, results in damage to the power supply.
Double-check your power supply voltage before you connect input power.
